Human machine interface for a controller



FIG. 1 is a front perspective view of a human machine interface for a controller showing our new design according to a first embodiment shown in an off state;

FIG. 2 is a front elevation view thereof;

FIG. 3 is a front perspective view of a human machine interface for a controller according to a second embodiment shown in an on state; and,

FIG. 4 is a front elevation view thereof.

We note that the human machine interface for a controller shown in FIGS. 1-4 can be used, for example, in transport applications. For example, the human machine interface can be for a controller used to control a transport climate control system. The transport climate control system can be used to control environmental condition(s) (e.g., temperature, humidity, air quality, and the like) within a climate controlled space of a transport unit (e.g., a truck, a container (such as a container on a flat car, an intermodal container, etc.), a box car, a semi-tractor, a bus, or other similar transport unit). The transport climate control system can include, for example, a transport refrigeration system (TRS) and/or a heating, ventilation and air conditioning (HVAC) system.

The broken lines in FIGS. 1-4 depict portions of the human machine interface for a controller that form no part of the claimed design.

The diagonal hatching shown in FIGS. 3 and 4 depict illumination in a on state. 

CLAIM The ornamental design for a human machine interface for a controller, as shown and described.
